 MR>Tom, *all* unbalanced antennas require a ground to work properly.

 TW> They why do Battery Radios work so well?

High sensitivity superheterodyne cicuitry and there is always a path
to ground though it is high impedance. If you ground it good the band
just lights up! The only radios that work at the best they can are
those with a balanced antenna because the ground is is not needed.

Think about it a minute, the unbalanced antenna picks up the energy
wavefront and now needs to dispose of the emf. Now ask yourself the
question what is the reference for this source of potential, is it the
radio or is it the Earth? Experiment with a galena or crystal radio
and see for yourself:
-> no ground = barely audible signal, good ground = loud signal
